If you could dream up the ultimate BB revolver, you probably would come short because ASG went beyond the imagination to make this 4.5mm BB revolver as believable as possible. The Dan Wesson revolvers use actual brass shells to load the BB's into the all metal cylinder. The Dan Wesson 4 inch version comes in a gloss black finish with the medium length barrel! It kind of reminds me of the 38 Specials the police used to use!
